detecting and determining that a fault occurs in an ice pulling-out component of the ice machine;
detecting that a switch of the ice storage bin has not been dislocated for more than a preset manual handling time period; and
controlling a heating component of the ice machine to heat based on one or more of a plurality of preset target temperatures that increase among one another in response to detecting the fault occurring in the ice pulling-out component and the switch of the ice storage bin not having been dislocated for more than the preset manual handling time period.
